摘要
蝴蝶拱桥是一种新型空间组合拱桥,设计巧妙独特,外型美观。为全面分析其力学行为,建立了空间杆系和板壳有限元分析模型,给出了该桥控制截面在几个主要荷载工况下的变形和应变值;为验证计算理论的合理与准确性,确保该桥的安全与可靠性,进行了1/10模型试验,并将理论计算值与实侧值进行了比较,为该桥的设计与施工提出了有意义的建议。
Butterfly-arch-bridge is a kind of newfashioned combined arch bridge which is aesthetic in appearance, and design of the bridge in is artful and particular. In order to roundly analysize the mechanical behavior of the bridge, spatial member and shell finite element model were established, further deformation and strain values of governable section under several main loading cases were listed; For ensure rationality and veracity of theoretical calculation and security and dependability of the bridge, model test with a scale factor of 0. 1 was carried out,then theoretical calculation values and test values were compared. Finally suggestions worthwhile about design and construction are provided through test and theory results.
